That’s right, move away from the sound source if possible and the decibel level will reduce. Turn down the volume on your personal stereo system (MP3, CD player, etc.), car stereo, radio, and television and speaker system. A decibel (dB) is used to measure sound level and provides a guide for what types of noise are harmful to hearing. Estimates from the World Health Organization suggest that hearing loss afflicts 28 million Americans.
Musician’s Earplugs (custom made to fit your ears): If you play in a band or frequent concerts, we recommend you get a custom set of musician’s earplugs. According to the American Osteopathic Association, “one in five teens has some form of hearing loss—a rate about 30% higher than it was in the 1980s and 1990s—which many experts believe is due, in part, to the increased use of headphones.” And once you lose it, you never get it back.
Perhaps the most dangerous thing that happens with hearing loss is that it’s not always easy to tell there’s a problem.
Do you have trouble following the conversation when two or more people are talking at the same time? If you answered “yes” to three or more of these questions, we recommend getting your hearing checked.
3) The basilar membrane inside the cochlea breaks the sound waves up into different frequencies.


4) Tiny hair cells which live on the basilar membrane translate mechanical vibrations into patterns of nerve impulses.
Your basilar membrane is lined with tiny hair cells, which are responsible for converting mechanical vibration of the basilar membrane to a chemical signal that stimulates your auditory nerve.
Hair cells in your ear come in two flavours: one row of inner hair cells and three rows of outer hair cells. The pictures below show electron micrographs of healthy hair cells (left) and hair cells after exposure to excessive noise (right).
Damage to the auditory nerve, indicated by the arrow, can cause sensorineural hearing loss. These earplugs will not block the sound but will filter it to a safer decibel level so that you can still enjoy the experience without damaging your hearing. Damage to your cochlea—the elegantly designed, snail-shaped part of your ear that detects sound—is permanent, so it’s critical that you treat hearing checks as part of your general preventative health, just like going to the dentist and your annual physical. Permanent hearing losses can go undetected for years before you decide it’s time to see an audiologist. At Hearing, Speech & Deaf Center we have a professional and caring Healthy Hearing Team waiting to serve you—please give us a call to schedule your appointment! The near ("basal") end of the basilar membrane resonates to high frequencies, and the far ("apical") end resonates to low frequencies.


The inner hair cells are heavily connected to the auditory nerve, and they send sound information to your brain.
As you grow older, hair cells at the high frequency end of the cochlea also tend to wear out.
But noise should not keep us from enjoying the activities we like to do and frequenting the places we love to go! Monitoring and managing your hearing health is part of a comprehensive preventative health program. Vibrations at different locations on the basilar membrane therefore reveal what frequencies are present in the sound. The job of the outer hair cells, in contrast, is to amplify the sound vibrations by dancing along. This little video shows you how the vibrations might look if the basilar membrane could be "rolled out in front of you".
